If you are a long-term Minecraft player, you probably came across the OpenGL error 65543 at some point during your gameplay. While this error goes away after restarting the game, it is quite annoying to have your game restarted all the time. 

Error message

The OpenGL error 65543 in Minecraft likely means there is a problem with your graphics card drivers. It can also indicate compatibility issues with your GPU.

To help you out, we’ve decided to make a guide for fixing the OpenGL error 65543 in Minecraft. 

Let’s get started!

1. Restart Your Computer. 

Whenever you encounter problems with Minecraft, the first thing you should do is restart your computer. 

This way, you can rule out temporary bugs or errors that may have occurred on your system or graphics card. 

Here’s what you need to do: 

  1. Access the Start Menu by pressing the Windows key on your keyboard. 
  2. Now, open the Power Options tab.

Once done, go back to Minecraft and see if the OpenGL error would still occur. 

2. Run Minecraft As Admin. 

Some configurations on your computer might be interfering with Minecraft and preventing it from accessing crucial resources. 

To ensure that Minecraft has access to everything it needs, run the game as an administrator. 

Follow the steps below to launch Minecraft as an admin: 

  1. Look for Minecraft on your desktop and right-click on it. 
  2. Now, click on Properties
  3. Go to the Compatibility tab.

Restart your system and see if the OpenGL error 65543 would still occur in Minecraft. 

3. Disable Antivirus. 

Antivirus software are third-party services that protect your system and files from malware and viruses. 

If you encounter OpenGL issues with Minecraft, your antivirus could be restricting the game from accessing your graphics card or other resources related to graphics rendering. 

To rule this out, try disabling your antivirus before playing the game. If possible you can add Minecraft to your antivirus safelist.

4. Adjust Graphics Settings. 

If you are using an older system, you might want to adjust Minecraft’s graphics settings. 

Although the game doesn’t appear to have fancy graphics, Minecraft can put a lot of load on your system, especially when your configurations are cranked up. 

Due to this, we suggest adjusting your graphics settings and lowering the render distance and graphics quality. 

Lowering Minecraft’s graphics settings should lower the load on your system and prevent the error from occurring. 

5. Update Your Graphics Drivers. 

There might be an issue with your graphics drivers that triggers the OpenGL error 65543 in Minecraft. 

To rule this out, update your GPU drivers to the latest version to patch any bugs or errors.

  2. Now, click on Device Manager to launch it.
  3. Expand the Display Adapters tab and look for your GPU.
